Fidosaurus is the brand name given to a range of dog-
biscuits. This name was chosen because when your dog is
eating one of these new biscuits, the effect is visually
similar to that of a large hairy dinosaur sized beast
chewing on an unfortunate small human victim.

This is due to the Fidosaurus
biscuit range taking the
form of a series of miniature human figures in various
'normal everyday" poses, such as: walking in the rain
with an umbrella; sitting on a bench reading a
newspaper; standing in a queue with hands in pockets.

Supplementing the 'normal range' is the 'terror range'
featuring figures in various attitudes of total panic.

The biscuits are quite detailed but not flimsy, meaning
that most dogs will need to chew, crunch and gnaw on
them (loudly) over time, perhaps abandoning them half
eaten for future consumption, or even burial.

When your dog begins eating, you can now film or
photograph it as the resulting horror reveals itself, of a
monstrous dog chewing on a miniature person who only a
few
minutes earlier was quietly reading their paper.

These dog biscuits should have slightly softer,
red-coloured interior for maximum effect. Also, I'm trying to think of the right additive which would generate smoke or steam when being chewed to give the right kind of fire-breathing Godzilla effect.

I'm happy enough with basic sound effects and
visuals. The efforts to introduce pyrotechnics are
welcome, but would probably cause any dog to
drop his crunchy biscuit and be very wary of them
in future.

Those last two values seem high, unless there's some misunderstanding.

A quick practical check has McVities Plain Chocolate Digestives at about 12g each, and individual dog biscuits such as Shapes and Gravy Bones in the 5 to 10g range. Bonios are bigger and heavier, but still nowhere near 140g.

You're forgetting that dogs range in size from tiny
Chihuahuas to Neapolitan mastiffs. That which
looks impressive in a small dog's mouth would be
swallowed hole by a bigger breed, so the
Fidosuraus range naturally comes as Small, Medium
and Large humans.

Larger effigies will require more material and take longer to print; thus if the biscuits are truly bespoke likenesses, individually generated, unit cost will be directly proportional to size, for small batches.

If you 3D print a multi-use mould, maybe not so much.

The HalfBakery: The only place in the known Universe where the economics of customised dog-biscuit manufacture are the subject of serious discussion ...

There is a company that sells customized dog treats > they're
still in business > so presumably they do things like basic
costing, overheads & pricing analysis > ergo there was indeed
a discussion of the economics thereof even if only as basic as
"so, what are we going to sell these for?"
